The main strength of these motors are that they
are small and compact. In its shortest design,
motor type GDM 12 N, only 39,5 mm of axial space
is required.
Two motor types are available.
DC Disc Motors
Baumuller DC disc motors are permanent magnet
motors with non-ferrous rotors and barrel commutators.
Conse-quently, they are low in inertia and highly
dynamic throughout the whole speed range.
Brushless Disc Motors
For applications where DC motors (with
their associated commutator and carbon brushes)
are unsuitable, brush-less disc motors are ideal.
The additional electrical control required for
any special applications can also be incor-porated
in the motor frame.
GDM 75 - 12 - DC Disc Motors
- Barrel commutator
- Ironless rotor
- Winding as a wire bobbin
- Given sufficient ventilation, and depending
on the type of winding, these motors are
able to provide peak
powers well in excess of their nominal
ratings; even capable of offering full
nominal torques at standstill
without sustaining thermal damage
- The inductance of the armatures is very
low, which is the reason for minimal wear
of carbon brushes. There- fore maintenance
costs can be substantially reduced.
- All of the GDM range permit a high dynamic
performance throughout the whole speed
range. Therefore, they are very well suited
to high transient loadings i. e. frequent
start/stop running modes
- Speed-regulated motor without any
externally mounted electronics
- Reduction in cost of cabling
- No additional installation of sensor
mechanisms, such
as tachogenerators or impulse transmitters/encoders
- Maintenance-free due to brushless
electronic commutation
- Flat construction

Brushless Disc Motors are manufactured
according to two different principles:
For the lower range (motors DSM 115) the principle
of DC disc motor is just reversed. The ironless
winding slips from the rotor into the stator,
the magnets slip from the stator into the rotor
where they can be built in the easiest way just
upon the rotating magnetic feedback. This type
of motor has no cogging effect on principle.
For the higher range (motors DSM 117 – 190) the
stator winding will be inserted into the slotted
armature with skewed stacks. The power output
can be increased considerably by means of the
smaller magnetic air gap. The cogging effect normally
existing on this type of motor is nearby completely
compensated by special means.
